WASHINGTON — A Democratic political action committee has released a series of digital ads targeting Republican Senate candidates in Nevada, Tennessee, Ohio, Missouri and West Virginia.

American Bridge 21st Century officials said the ads are part of a national six figure ad buy. They focus on the Trump administration’s announcement that the health care provisions in the GOP tax bill make coverage of pre-existing conditions unconstitutional.

"Republicans own the mess they’ve made of our healthcare system — from driving up costs to trying to end coverage for preexisting conditions — and you can guarantee Democrats will hold them accountable every day through November,” spokeswoman Amelia Penniman said.
